Answer:

Step-by-step explanation:

Answer

Correct option is

A .1

Given, m  

2 =4+5m⇒m  

2 −5m−4=0

Compare the given equation with  ax  2 +bx+c=0

Since, x=  2a −b+  b  2−4ac

​ and x=  2a −b− b 2−4ac

​ In given quadratic equation  a=1,b=−5,c=−4

∴m=  2a −(−5)+  (−5)  2 −4×1×(−4) and  

m=  2a −(−5)−  (−5)  2 −4×1×(−4)

​ ∴m=  2 5+ 41  and m=  2 5−  41  

∴m=  2 5±  41

 

 

Thus given statement is true
